3D Shape and Motion Analysis from Image Blur and Smear: A Unified Approach
This paper addresses 3D shape recovery and motion estimation using a realistic camera model with an aperture and a shutter. The spatial blur and temporal smear e ects induced by the camera's nite aperture and shutter speed are used for inferring both the shape and motion of the imaged objects.
متن کاملDiagnosis from the blood smear.
A related slide show is available at www.nejm.org n examination of the blood smear (or film) may be requested by physicians or initiated by laboratory staff. With the development of sophisticated automated blood-cell analyzers, the proportion of blood-count samples that require a blood smear has steadily diminished and in many clinical settings is now 10 to 15 percent or less. Nevertheless, the...
متن کاملتولید اتوماتیک مدل رقومی زمین از یک تصویر با استفاده از تکنیک shape from shading
پیشرفت در علوم الکترونیک و کامپیوتر در چند دهه اخیر، شرایط مناسبی جهت گسترش علم و فن فتوگرامتری فراهم نموده است، بطوریکه پژوهشگران در زمینه خودکارسازی مراحل مختلف فتوگرامتری رقومی، گامهای بزرگی برداشته اند. مدل رقومی زمین (digital terrain model) به عنوان یکی از مباحث مهم در فتوگرامتری مطرح بوده و تاکنون روشهای مختلفی جهت تولید آن مورد بررسی قرار گرفته است. تکنیک (sfs) shape from shading...
15 صفحه اولShape Semantics from Shape Context
3D models play an important role in many industrial applications. Therefore semantic processing for the purposes of comparing, cataloging and archiving shapes is a major concern. Most previous work considers comparisons based on the object’s overall geometry or in a reference frame which is computed from the object’s geometry alone, disregarding its context. There are also approaches which prop...
متن کاملCombining shape, texture and intensity features for cell nuclei extraction in Pap smear images
In this work, we present an automated method for the detection and boundary determination of cells nuclei in conventional Pap stained cervical smear images. The detection of the candidate nuclei areas is based on a morphological image reconstruction process and the segmentation of the nuclei boundaries is accomplished with the application of the watershed transform in the morphological color gr...
